The SCB series of epoxy resin cast dry-type power transformers is suitable for three-phase, 50 Hz, distribution grid systems. These transformers are used for the input of the primary side of the grid and the output of the secondary side to realize voltage conversion of the primary and secondary sides. This series off transformers conform to international/national standards such as IEC 60076,GB/T10228,GB1094 and GB20052-2020.The integrated temperature controller is used to duly monitor the temperature state of the transformer, and control the output of the over-temperature alarm and over-temperature trip to ensure safe operations of the transformer and prolong its operating life.

High-quality cold-rolled grain-oriented silicon steel sheets with high magnetic conductivity are selected, and the core is laminated by the GEORG stacking robot, which greatly reduces no-load loss, no-load current and noise; while the surface is coated with resin paint to prevent moisture and rust and reduce noise.

The coil is made of high-quality copper wires; the filled epoxy resin is cast in vacuum to form a thin insulation structure with a bright and elegant appear-ance. Larger-capacity coils are designed with axial air passages to ensure the heat dissipation capacity and the partial discharge of less than 5pc.

The coil is made of high quality copper foil by an automatic foil coil winding machine, and the internal welding is protected with argon, featuring high weld-ing quality and low welding resistance; the DMD is selected as the interlayer insulation and curing is carried out in the oven without casting.
